Abstract
The wall downstream of the slot of an ejector forms a divergent angle relative to the upstream wall adjacent to the slot so that the flow discharging from the slot expands and avoids having the primary air from pinching the secondary air and adversely affecting the cooling film issuing from the slot. When multiple slots in the ejector are utilized the downstream wall in relation to the upstream wall is similarly configured to obtain local multi-expansions.
